Has anyone read/heard about the textbook Variational Principles in Classical Mechanics, written by Douglas Cline? Any thoughts on whether I could use it as a replacement for Goldstein?

Thank you!

My class used Marion's book now Marion and Thornton (5th edition). Its pretty good although when I read Goldstein felt it was a better / more advanced book.

Here's an old thread discussing various CM books.

It seems like an interesting book, and it's quite cheap. I'm tempted to buy it since I'm always happy to know a new/different classical mechanics book.

Variational principles in classical mechanics are mathematical equations that describe the behavior of physical systems. They are based on the idea that the actual motion of a system is the path that minimizes or maximizes a certain quantity, such as energy or action.

Variational principles are used to derive the equations of motion for physical systems in classical mechanics. They provide a concise and elegant way to express the fundamental laws of motion, such as Newton's laws, and can also be used to derive more complex equations, such as the Euler-Lagrange equations.

Variational principles are significant because they provide a powerful and general framework for understanding and predicting the behavior of physical systems. They also allow for a more efficient and elegant approach to solving complex problems in classical mechanics.

Variational principles have a wide range of applications in various fields, such as astrophysics, optics, and fluid dynamics. They are used to model and predict the behavior of celestial bodies, design optical systems, and analyze the motion of fluids, among others.

One limitation of variational principles is that they may not always provide the most accurate or precise predictions for physical systems. They also require advanced mathematical techniques and may be difficult to apply in certain situations. Some critics also argue that the concept of minimizing or maximizing a quantity may not always accurately reflect the true behavior of a system.
